在水溶液中，晶体结构难以观察到戊胺与牛胰酶的结合，在环己烷中，一个戊胺分子结合在胰酶的活性中心，同样酶表面观察到了更多的硫酸根，这些都进一步验证了有机溶剂中静电相互作用加强。

Precursors of sulfates and alkali halides prepared in co-deposition process were mixed homogenously, annealed at high temperature and then formed CoO and NiO fibers, XRD, XPS, Raman and SEM were used to characterized the samples, the growth of these fibers might be a special LS mechanism: soluble precursors in molten salt decomposed gradually to form initial crystal nucleus and succeeding particles adhered to these nucleus and grew anisotropically in the special high temperature fluent medium, the higher decomposition temperature and solubility of the precursor are two key factors in this method, which are in favor of a longer growth process and result in larger sizes of the final metal oxides crystals.

以共沉淀方法生成硫酸盐与碱金属卤化物融盐的均匀混合前驱物，在高温下退火制备出了CoO和NiO的晶须，以XRD和XPS等对成份进行了分析，SEM分析了形貌特征，研究了不同前驱物热分解特性，认为本方法是一种简单的LS生长机制：可溶性前驱物于融盐中热分解后逐渐析出成核，后续的粒子附着在核上，在融盐环境下沿一定方向作准一维生长，其产物形貌之不同源于硫酸盐的高分解温度和在融盐中的可溶性，导致晶体生长过程中成核过程与生长过程竞争的结果对一般前驱物结果的偏移。

Common fillers are various silicates, carbonates and sulfates such as clay, limestone, calcium carbonate, magnesium carbonate, barytes, etc. Water is added to produce a filler that spreads easily when applied and drys into a hard mass.

普通填料有各种硅酸盐，碳酸盐和硫酸盐，如粘土，石灰石，碳酸钙，碳酸镁，重晶石等水是增加生产填料容易传播和应用时drys变成硬肿块。
